摘　　要：味精废水具有COD ,SO2 - 4,NH3 -N浓度高 ,pH低等特点 ,是目前工业废水治理的难点之一。南宁味精厂中高浓度味精废水处理工程采用高效好氧生物处理反应器 (HCR) 生物接触氧化池 (BCO)组合工艺 ,能有效去除废水中的COD ,且不受高SO4 2 - 的影响。HCR和BCO对COD去除率分别达到 75 %以上和 5 0 %以上。但该工艺对NH3 -N的去除效果欠佳 。The monosodium glutamate production wastewater has high level of COD, sulfate and NH 3-N with low pH value. High performance compact reactor (HCR) and biological contact oxidation (BCO) were introduced to treat the medium high concentration monosodium glutamate production wastewater. The effluent of this facility is stable and quite good to meet the requirement of national wastewater discharge standards. The COD removals are greater than 75% and 50% for HCR and BCO respectively. However, the removal of NH 3-N of this process is not satisfied.
